I had this happen to me once earlier in BFA. We wiped in Kings Rest and me and two others were joking around about it while waiting for the last guy to show up, most of us were having a good time talking but then one dude said "Can you guys just stfu and focus on the boss so we can actually kill it jfc"
So I naturally said "Well bucko you were the one hitting the wrong totem and not stacking so why don't you stop telling us what to do and read that dungeon journal "
He didn't say anything else for the rest of the dungeon
